AM3352 / Re: Touchscreen compatibility ...
Last post by Christopher23 - May 17, 2024, 07:22:53 AM
A good choice for a small touchscreen that is compatible with the AM3359-SOM-EVB-IND is the 4.3-inch LCD with resistive touchscreen from Waveshare. This monitor has a resolution of 480x272 and comes with a USB touch control board, making it easy to connect to the AM3359-SOM-EVB-IND via USB port.

Last post by djpeterlewis - May 17, 2024, 01:49:00 AM
I did a test with another supplier of a board using WLED as well using the same settings on Ethernet and their board did not flash pixels. I was hoping it would have been the WLED software as it is a easier fix.

Can you guys look into it ?

I want to standardize my products using your board. So far I have over 100 boards and they all seem to give the same issue

Thank you

ESP32 / Serial Monitor with ESP32-S2-D...
Last post by dwd - May 16, 2024, 08:25:46 PM
I suspect this is a silly question, but I cannot get the Serial Monitor to work with this board. I can put it into boot-loader mode and upload a sketch, then RST and run it. However, when I RST the board so it runs, the Arduino IDE (Version 2.3.2) loses contact with the board and so cannot display anything.

What am I missing?

Minimal code to reproduce:
Code Select
#define PERIOD  1000  //ms

void setup()
{
  Serial.begin(115200);
}

void loop ()
{
  Serial.println("Hello World!");
  delay (PERIOD);
}

A20 / Building u-boot for A20-OLinuX...
Last post by luimarma - May 16, 2024, 10:34:19 AM
Hello,

I am trying to compile u-boot for the A20 Olinuxino micro with emmc, for the current Bullseye image with olimex 5.10.180-olimex kernel.
The reason is to avoid some drivers checking and speed up booting.

I have started just compiling with the default configuration, but the resulting u-boot is not applying the overlays in /boot/uEnv.txt

The procedure I have followed is the next one:

I have downloaded the source from here, https://github.com/OLIMEX/u-boot-olinuxino
Next applied the following commands to set the default config and compile.

#make CROSS_COMPILE=arm-linux-gnueabihf- distclean
#make CROSS_COMPILE=arm-linux-gnueabihf- clean
#make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino_MICRO-eMMC_defconfig
#make CROSS_COMPILE=arm-linux-gnueabihf-

And finally to install the new u-boot and make sure that all is consistent, I did the following.
copy u-boot-sunxi-with-spl.bin to /usr/lib/u-boot-olinuxino/a20-olinuxino/u-boot-sunxi-with-spl.bin
#u-boot-install /dev/mmcblk0
#/usr/sbin/update-initramfs -u
#/etc/kernel/postinst.d/uboot-fit 5.10.180-olimex

When booting with the new u-boot the board boots, but I no longer see the overlays reflected at uEnv.txt loading, before I could see the following output after the FIT image overlays:

ESP32 / Re: ESP32-WROOM-32E-N8 - LoRa8...
Last post by Steff - May 16, 2024, 10:30:28 AM
Yes it works  ;D

My Code is based on https://github.com/lnlp/LMIC-node and i'm using platform.io in VSCode.
Thanks to LubOlimex this post directed me in the right direction https://forum.mcci.io/t/olimex-mod-lora868/264

Created /include/HalConfig.h
Code Select
// HalConfig.h

#ifndef _HalConfig_h_
#define _HalConfig_h_

#include <arduino_lmic_hal_configuration.h>

class MyHalConfig_t : public Arduino_LMIC::HalConfiguration_t {

public:
    MyHalConfig_t();
    virtual TxPowerPolicy_t getTxPowerPolicy (TxPowerPolicy_t policy, int8_t requestedPower, uint32_t frequency) override;
};

#endif
then created src/HalConfig.cpp
Code Select
// HalConfig.cpp

#include <arduino_lmic_hal_configuration.h>
#include "HalConfig.h"
#include "Boards.h"

#define LMIC_FORCE_POWER_POLICY Arduino_LMIC::HalConfiguration_t::TxPowerPolicy_t::RFO

// Init
MyHalConfig_t::MyHalConfig_t(){};

// Override getTxPowerPolicy
Arduino_LMIC::HalConfiguration_t::TxPowerPolicy_t MyHalConfig_t::getTxPowerPolicy (
    Arduino_LMIC::HalConfiguration_t::TxPowerPolicy_t policy,
    int8_t requestedPower,
    uint32_t frequency
) {
    LMIC_API_PARAMETER(policy);
    LMIC_API_PARAMETER(requestedPower);
    LMIC_API_PARAMETER(frequency);

    #ifdef LMIC_FORCE_POWER_POLICY
        return LMIC_FORCE_POWER_POLICY;
    #endif

    // default: use PA_BOOST exclusively
    return Arduino_LMIC::HalConfiguration_t::TxPowerPolicy_t::PA_BOOST;
};

Create src/baords/sbc_olimex_v1.h (copy from bsf_ttgo_lora32_v1.h)
I've changed the definitions, added include and myHalconfig and changed the pinmap
Code Select
#pragma once

#ifndef BSF_SBC_OLIMEX_V1
#define BSF_SBC_OLIMEX_V1

#include "config.h" // from packages/toolchain-xtensa-esp32
#include "LMIC-node.h"

#define DEVICEID_DEFAULT "sbc-olimex-v1"  // Default deviceid value


#ifndef LMIC_CLOCK_ERROR_PPM
    #define LMIC_CLOCK_ERROR_PPM 0
#endif   

// https://forum.mcci.io/t/olimex-mod-lora868/264/2
#include "HalConfig.h"
static MyHalConfig_t myHalConfig{};

const lmic_pinmap lmic_pins = {
    .nss = 5,
    .rxtx = LMIC_UNUSED_PIN,
    .rst = 21,
    .dio = {26, 33, 32},
    .rxtx_rx_active = 0,
    .rssi_cal = 10,
    .spi_freq = 8000000,
    .pConfig = &myHalConfig
};

// nothing changed after this.
platformio.ini
Code Select
[platformio]
default_envs =
  sbc_olimex_v1 ;added new

[common]
lib_deps =
  olikraus/U8g2 ;even if there is no oled. make sure it is included. Otherwise i got compiling errors - OLED display library

[esp32]
build_flags =
-D hal_init=LMICHAL_init


[env:sbc_olimex_v1]
platform = espressif32
board = upesy_wroom

    -D BSFILE=\"boards/sbc_olimex_v1.h\"
    -D MONITOR_SPEED=${common.monitor_speed}
    -D LMIC_PRINTF_TO=Serial   
    -D USE_SERIAL

There are a lot of other configs in the platformio.ini. I reduced it to the changes and important things.

I hope I didn't forget anything  ???

ESP32 / Re: ESP32-gateway...different ...
Last post by LubOlimex - May 16, 2024, 08:19:45 AM
There are major changes between those two revisions.

> i installed mini lcd in both units to pin 11-12-13-14 and i connect pins 12 to 9....in revision E it's correct work, but in revision G no...

GPIO9, GPIO10, GPIO11 in revision E shouldn't be used in first place since they are connected to the internal memory. In newer revision they were completely re-routed from the headers so that you can't affect the memory. Probably one of these two major changes affect your work:

- GPIO6-11, which are used by the ESP32's internal flash, were disconnected from CON1 and the 6 SD card signals are now routed instead for use when SD card is not present;
- SD card changed from 4-bit mode of operation to 1-bit mode of operation! Added 3 NA resistor pads (R9-R11) for backwards compatibility.

You can find full revision changes and track the changes that occured from revision E to revision G here:

Last post by LubOlimex - May 16, 2024, 08:11:50 AM
Did it work? If yes, and if and when you have the time can you make a short post with description and maybe code on how you get it working. That would be helpful for a lot of people. The problem we face with the LoRa boards is that we don't have any public TTN network anymore in our town to help us test (we used to have a couple of such points, but they are no longer operational).Thank you in advance.
