I am working on creating a reverse phase dimmer where the on/off timing for the 120/240 VAC sine wave is handled by an STM32L051C8Tx MCU. There is a separate analog circuit that generates a 3V3 pulse at every zero crossing and I take this as an input...
I have a system that uses an STM32L476 controller, where we are using EXTI0 to wake up on a falling edge interrupt.My interrupt service routine used to wake up, contains an IWDG reset, so any time the interrupt gets serviced, we just reset (that's th...
I've been trying to setup the DMA on UART Receive on both the STM32H7 and F7 nucleo boards however I can't seem to get it to work. I can get the DMA on transmit to work fine but whenever i send anything to the board, either by hard wiring UART2 TX to...
Hi there,in the new MotroControl SDK there is a new ESC listed with a STM32g431. The only document that I was able to find was UM2516. Is there some more info about availability and the usual product web site? Best regards,Ingo
Hi all, I have some issues getting my DMA to interrupt correctly on my STM32F411RE. I recall that I previously had this working correctly, but even with my old code and solutions offered on this forum I cannot figure out what I am doing wrong at the ...
Hi everyone I am trying to implement I2C Write and Read with DS3231. I am using stm32f051r8t6. I do not want to implement this using CUBE. Kindly help me in identifying the mistakes I have done. I am able to write and read but what I write does not a...
Dear Members,I want to count pulse from EXTI4, and I tried to set 30 seconds for how many pulse ?Please correct my setting :void MX_TIM4_Init(void) { TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; ...
I have a weird problem with one of the boards that I am trying to flash with a custom boot loader.Consider the following snippet:Reset_Handler LDR R0, =SystemInit BLX R0Most people will recognises it as being the first two ins...
