error description:I wrote a function to change the UART parameter! After using this function, the UART parameter worked as installed but when the data was sent, the UART interrupt function changed a global variable of I am back to 0!Everyone can see ...
Hi!We have an application which runs on PIC24H, we would like to port it to another MCU. Application is extremely time critical, meaning that we need extremely deterministic code behaviour. In short, there are pulses which are obtained via special ha...
We have used PE6 GPIO for STM32 standby entry and PE6 is configured as initially as EXTI input mode in pull-down configuration. When there is high to low transition on PE6 STM32 jumps to standby mode. We are also using the same GPIO for coming out fo...
First time using a STM32F4 for I2S.I don't use your libraries as I want to understand the cpu at the register level.I set up the I2S PLL and enable the I2S clock.When I start to write to the SPI4 registers, they are not accepting the data. I have fo...
Hi,I am trying to use Host Negotiation Protocol on STM32 boards.Two boards are connected together stm32f4-discovery (A-device) and stm32f429i-disc1 (B-Device). VBUS sensing, HNPCAP is enabled at both side.DHNPEN bit in GOTGCTL register is enabled aft...
Posted on July 06, 2018 at 09:56 Hi guys, I have a nucleo board of a STM32L4 and I'm trying to test the Power Consumption in the different Low Power Modes. I read the examplePWR_EnterStopMode and viewed a few discussion in the community for...
I have a CAN-bus network and there is one host and 2 "slaves", all implemented inside STM32F446 micrcontrollers. To save power, I put them into Stop Mode when they're idle. In order to wake up from Stop Mode, I subscribe to external interrupt on CAN ...
I am working with the STM32F446 microcontroller and I would like to create a versatile timer function using the RTC:typedef void (*timerCallback_t)();void scheduleOneTimerEvent(uint32_t timeoutMs, timerCallback_t timerCallback);I am considering using...
Is it possible to do this? I need to shift PWM2 by 180 degrees from PWM1. On a test board I am doing this with two timers, with the second timer picking up the count from the first and adding period/2. The current board will not allow this.I hope it ...
I am trying to build a system that does not use interrupts at all. This due to hard realtime requirments. Now I hat a look at the HAL code and as far as I can see even HAL_I2C_DMA functions seem to rely on IRQ, correct?Can HAL I2C DMA functions be us...
