How to control a wired light switch with M5 Atom

konacurrents — Mon, 20 May 2024 20:20:06 GMT

The r-relay-unit looks promising. But how do I get power to the controller (M5 Atom, etc)? thanks,

M5Stack.h: No such file or directory with M5StickCPlus?

wsanders — Wed, 08 Feb 2023 20:22:00 GMT

@wsanders At least with respect to the LCD library: The only function implemented so far to manipulate whole images is drawBitmap. drawJpg and drawJpgFile are commented out in https://github.com/m5stack/M5StickC-Plus/blob/master/src/M5Display.h so I assume they aren't working yet. So my workflow for now is: Save the image from gimp in gimp's ".h" format. This is smaller than a xpm or bmp. You will get a static char *data structure of all the pixels in the image. The .h file includes a macro to extract the pixels: #define HEADER_PIXEL(data,pixel) { pixel[0] = (((data[0] - 33) << 2) | ((data[1] - 33) >> 4)); pixel[1] = ((((data[1] - 33) & 0xF) << 4) | ((data[2] - 33) >> 2)); pixel[2] = ((((data[2] - 33) & 0x3) << 6) | ((data[3] - 33))); data += 4; } Write your own function rgb888to565 to compress the pixels into a uint16_t. Draw a bitmap of the image as fast as you can: #include #include "1.h" int pixel[3]; // pointer fu to preserve the start of .h data char *datastart; uint16_t *bitmap; void setup() { M5.begin(); M5.Lcd.setRotation(3); bitmap = (uint16_t *)malloc(height * width * 2); } void loop() { M5.Lcd.fillScreen(GREEN); datastart = data; for (int16_t y=0; y < height; y++) { for (int16_t x=0; x < width; x++) { HEADER_PIXEL(data, pixel); bitmap[60*y + x] = rgb888to565(pixel[0], pixel[1], pixel[2]); } } M5.Lcd.drawBitmap(0,0,width,height,bitmap); data = datastart; } Or you can use the Sprite library, which works well.

Stange interaction between clock and temprature sensor setup

EricR — Thu, 01 Sep 2022 12:04:21 GMT

Hi @felmue and thanks for the help. I changed GPIO and it works now. Strange as input port 2 worked when the temperature sensor were implemented separably. However I have spend enough time trying to make it work. So I will not conplain now that it is working. Thanks again

Stamp Pico USB Serial

HannesKannes — Wed, 24 Nov 2021 20:06:30 GMT

@felmue said in Stamp Pico USB Serial: Or in other words, there is no way to directly connect D- and D+ from the USB-C breakout to the M5PicoStamp. Hi Felix, thanks alot for that information. Was hoping this converter could be easy be done by some ICs and restistors maybe but would be too difficult for me yet. So i think i will get another controller with built in or a cojntroller with onboard USBC connection. Makes no sense to spend much time and money if the device will be procudes 100 times each with MCU and a serial converter. Your help was great!!! Best regards Hannes
