Hi all,Im using STM32F410 uart 1 to transmit and receive.I use DMA to transmit bytes. I then use TC interrupt to send a break,then push an event to an event queue to signal that the transmitter is free.void interface_uart_tx_eot_isr(if_uart_t* p) { ...
We are using the STM32H7R7L8H6H microcontroller in our product design.During firmware initialization, we observed inconsistent behavior related to the USB voltage detector on different boards that share the same hardware design and firmware.Specifica...
Being fairly new to the STM32 architecture I find the following statement in the STM32F103 reference manual really confusing ... "..., this means that only one request must be enabled at a time." (the same also applies to the DMA2 controller). I thin...
Hi,I am trying to get USBPD running. I need a simple example code without RTOS. So I used CubeMX. As far as I see it should be easy. All I need to do is:- Turn on the UCPD1 under Connectivity. Here I set "Source". - Turn on the UCPD1 Interrupt- Turn ...
Hello, I have an STM32F777ZIIT which is being used to gather SPI data in receive-only mode on four SPI channels and using DMA to buffer this data. The DMA buffers are 70 half-words long, configured for circular mode, and half the half-full and full i...
Hi. I designed a stm32 board an am trying to program it with a stm32 development board. i am having issues with programming it. This is my board design and my programming setup. I have connected the stm32f4 to my laptop to program it and the Integrat...
I am trying to program my custom board with STM32WB15CCU6E on it in Arduino IDE. I always upload the code to my nucleo-wb15 board to verify if it is working before uploading it to the custom board. The main difference between the chip used on nucleo-...
Hi,I want to use STM32G431CB or STM32F411CEU6 to measure the time precisely.I need to know the external interrupt response time of GPIO,but I can not find it in datasheet and manual.can you tell me what is the value if the CPU frequency is 100MH...
Hi,I am using an STM32U545 on which I expect to use ADC4_IN1 and ADC4_IN18 in stop mode 2 (using LPBAM).I want to create two buffer (buff1 and buff2 uint16_t[32]) dedicated to each input.I want to read 32 samples from input1 then 32 samples from inpu...
Hi everyoneWe have designed a custom board around the STM32L081CZ and produced 3 prototypes. On the first board I started testing and debugging using STM32CubeIDE on Windows. This worked fine but only with ST-Link, not with J-Link.After testing (and ...
