 Hello,I have designed a PCB with 3 STM32H725VGT6 MCUs, and assembled them according to my schematic:(sorry for this resolution, this is from a converted pdf)All 3 MCUs are the same, from this schematic.R5 and R2 are just 0R jumpers to select the boo...
Hello,I have implemented 4 wire SPI for my SSD1362 OLED controller. Here are my SPI transfer functions (both normal and DMA) void HAL_SPI_TxCpltCallback(SPI_HandleTypeDef *hspi) { // Deselect when Tx Complete if (hspi == &hspi1) { HAL_GPIO_WriteP...
Hello,I would like to know whether I understood the application note about the Vcap pins correctly. If there are 3 Vcap pins on the package, then 2 capacitors should be placed and one has to be connected to another. I'm not sure about this connection...
Hello,I have 3 different ADC inputs with DMA (ADC1, ADC2, ADC3). They represent different values like temperature, voltage etc.I was wondering whether it is possible to implement multiple arm_fir_f32 functions with the incoming data, but completetly ...
Hello,I have written my 4 bit grayscale, 256x64 OLED driver using SPI, and I want to visualize my throttle position. The throttle value ranges between -100 and +100 where -100 means maximum deceleration and +100 the maximum acceleration. So far, I ha...
