I have chosen the STM32H743 as the custom hardware chip to manage real-time applications, including displaying analog ECG data on a 1080x600 DWIN display with CTP and using a 24V thermal printer for printing. I need reference schematics for using SDR...
Hi, looking at the scheme it seems possible to power the board by providing an external 5V supply on the 5V Arduino PIN (CN5, pin 5, which is the output of the linear regulator feeded by V_IN), and removing all the jumpers on the CN1. Is it correct? ...
I'm doing an MTTFd, just wondering what the failure modes are for this processor. I.E Outputs stuck high, output
Hello,I have programmed one of the advanced timers in up/down mode and I have used one of the compare units to generate a PWM signal.I would also like to generate an interrupt on compare events, but only on the falling edges.Is it possible to specify...
Hey,in the past we used a STM32F4 and in the new Gen I will use the a STM32U5 and there is my questen about the cryptographic firmware in the past we could use the libSTM32CryptographicV3.0.0_CM4_GCC.a but now is there also a Lib for the stm32u5?
Hello, I'm using the nucleo-h743zi2 board.When obtaining the value of TIM2->CNT (or TIM5->CNT) through the combined channels of TIM2 or TIM5 on this board, without any special settings, I can perceive the encoder rotating in reverse as a negative val...
Hey. I am working on a task which requires to measure time between 2 different impulses with high precision. We have custom board that generates output pulse based on the capacitor and resistor values. The Input is LOW to HIGH impulse (Green color on...
Hello,I'm trying to use interrupt + dma to capture port D data input, and the interrupt occurs but DMA is not starting to work at all.Here is my code: void HAL_DMA_TransferComplete(DMA_HandleTypeDef *hdma) { if (hdma->Instance == DMA1_Stream0) { u...
I can not connect my STM32H735G board via ST-Link anymore. "no stm32 target found". I tried "connect under reset" (ST Link Utility and ST programmer) as well as connecting boot0 to VDD. Any idea how to erase the flash and start over? Cheers Stefan
Hello everyone! I can't figure out what my mistake is, from the next code, I have the same values for CH0 and VREF (I read others' replies but they don't work for me).What I'm doing wrong?//------------------------------------------------------------...
