Resolved! How to erase pages on bank 2 on stm32g4?
I was trying to erase some flash pages on an stm32g474re nucleo (and on a custom board with the stm32g474veh3).The flash pages are all on flash bank 2, because i read in the reference manual that flash bank 2 can be written while code is running from...
STM32G473 UART DMA free run not active but in trace mode it's work.
Hello,I make STM32G473 UART DMA work in debug trace mode (ST-LINK V3).when I disconnect wire and power off to reset for free run.it's not work.I don't understand.
USB CDC communication failure due to EMI
Hi everyone,We are facing issues with USB in our new products due to EMC (electromagnetic compatibility). IEC61000-4-4 burst, mediuum severity.The USB stops working fequently when the device is connected to a PC and a burst is applied to the AC power...
I am looking for help with DMA channel memory to a peripheral for a timer.
I am not sure how to handle DMA channel from memory to peripheral. I have a circular buffer of 2*24 words that I want to load to PWM. I want to update(generate) new values once half and top of the buffer is reached. I was using similar thing for ADC ...
How can a UART communication burn an MCU?
I am using the STM32f4-Discovery board, with the stm32f407vgt6 mcu. I am using it's USART peripherals at pins PB10 and PB11. Upon connecting another device to the USART communication something in the MCU failed, and now the board is not working prope...
HAL_UART_Receive_DMA has an unfindable hickup.
Hello,I'm working with UART Communication between a RPi and an STMG070RB. For the UART communication I'm using the library function HAL_UART_Receive_DMA.I have an initialize in which the Receive function waits for 3 bytes to be received (My messagehe...
Resolved! style RM0316
RM0316The reserved space is clearly indicated at the top, and the style changes abruptly on the next page, and the reserve is no longer specified. what is the result of missing addresses ? why can't a single style be maintained ? for clarity.
Resolved! Sending Serial Data from one UART to another. HAL_UART_Receive not reading new bytes.
My Board is the STM32-G431KB Nucleo-32. I have a Mavlink Serial Tx/Rx (From a PX4 Autopilot) connected to PA10/PA9.I am attempting to receive serial data at 115200 8N1 on UART1 and then send it at the same rate on UART2. I am just doing a basic polli...
Add CubeMX support for dual buffer DMA in ADC modes.
This is a suggestion, not a question...There's no support for dual buffer DMA mode in the ADC HAL, and it would be very easily added.Already did my own copying the existing function for the multimodeDMA.The problem is that CubeMX will wipe the code a...
