Hy.I have a little problem. I developed an Ethernet based remote firmware update for the STM32H753 uC (rev. V) in a custom board.The processor erases the BANK2, and than programs it with the new firmware. When the programmed firmware checks correctly...
Background: I use the stm32373c evaluation board to make project. One part of the project is to use the 16bit SDADC to acquire sinewaveform generated from function generator and send the data to pc sw thr. uart. I follow the evaluation board example ...
What I am trying to do:Send and receive data via USART on my STM32H7B3I-DK. I am connecting a serial USB to the STMod+ CN10 RX and TX and have 2 serial consoles on for monitoring the data that is transmitted on both ends (the serial USB and the disco...
Is there any example for using CAN1 and CAN2 in a dual CAN MCU like the STM32F777, especially how to configure the filter bank using the ST HAL (cube) ??As I understand the filter bank is shared. Are the FIFO0 and FIFO1 also shared?Why is there a CAN...
If there are more than three interrupts triggered simultaneously in the interrupt service routine/callback, how many nested interrupt the board can handle simultaneously. Or there are some cases of memory stack overflow which can lead to the dumping/...
Hello everyone.Any tips/pointers about where to look for info about how to write an arduino library using stm32's hal?Im a bit confused/scared about mixing c++ and c. (also scared of arduino underthehood non chip specific configs) All stm32 related l...
I am trying to connect an SPI communication device and a UART communication device to my STM32H7B3I-DK using the STMod+. From the datasheet for the discovery board, SPI and UART use the same lines (pin numbers 3 and 4) to connect the connections on t...
When using DMA to realize a SAI transmit (double buffer, rearmed in HAL_SAI_TxCpltCallback), I found some very strange behavior.In some configurations, a FIFO error interrupt (FEIF, ref. manual p. 235) happens after a few seconds. The time until this...
I'm using an STM32H725 and am trying to read a block of SPI data (say, 100 samples) from an external SPI ADC on a fixed sampling schedule. That is, I do NOT want to read all 100 samples as fast as possible; I want to read 1 sample every microsecond.I...
General objective: Generate 2 PWM's on Timer 3 and Timer 4 respectively at 50% duty cycle, both with period of 2 seconds and phase shift of 1second between them (Timer4 will start 1 sec later).Because I want it to be precise, I am not considering usi...
