Resolved! Strange interference between I2C1 DMA and USART1 interrupt (BARE METAL)
Hello,first of I must state that this is a bare metal project. If bare metal is not your thing then please do not read on. I only use parts of the CMSIS but no HAL and no LL.I have a strange effect when using I2C1 bus with DMA and USART1 with receive...
Getting HAL_ERROR while using I2C in Fast mode pulse
Hi All,I trying to interface MAX6651 Device using I2C module using STM32F410C8U6 MCU.Device address is 0x36 But when i'm using HAL_FMPI2C_IsDeviceReady(&hfmpi2c1, 0x36 , 2, 100); this API returning the valueHAL_ERROR.Here are some snaps Anybody look ...
STM32 HRTIM BURST DMA CONFIGURATION
Hi all,I am trying to configure burst dma on my board (stm32g474). I have successfully configure the dma for single register, however, when I want to configure dma for more than one register, I failed to do that as it only allow me to fill one addres...
STM32G0B1 Options Bytes
Dear, I currently use a STM32G0B1 on a custom board ans all worked fine until now. My firmware change the options bytes at running to disable the dual bank and using and single bank Flash.At the power up, the firmware check the options bytes and chan...
Triggering the input PWM or output PWMs using the HRTIM on STMG4
Hello,I'm currently using the HRTimer (on a STM32G474) for duplicating a input PWM signal. That means that in my case, I have one PWM input coming on 2 events (1 for the rising edge, 1 for the falling edge) and the outputs of the HRTimer B, will be s...
Resolved! Problem with I2C Interface on STM32F469I-DISCO
Hello, I am trying to write something on the I2C bus to a digital potineometer using the STM32F469I-DISCO board but I get no result, even no response from the device and its like there is no device connected on the bus. I tried the same potineometer ...
Resolved! How to switch a pin between open drain and ground
Hi, I have a pin labeled "DISABLE_HV" that I want switch between open drain and ground (and vice versa) to switch-off and switch-on a DC-DC converter. How can I implement this functionality in the code using HAL library?
Resolved! LPTimer counts only to 1 if running on LSE
Hi, I'm using on a STM32L4R9 a LPTimer1 in interrupt mode. If i use it with the PCLK1, HSI or LSI as clocksource it works as expected. It counts to the ARR value and then the interrupt occours. If i use the LSE as clocksource the LPTimer seems only t...
Resolved! How to set up APS512XX RAM in 1K burst mode on the STM32U5A9J-DK board
I am trying to set up the on-board 512Mb AP PSRAM to have a 1K word linear read burst.Similar to the HSPI demo in the BSP example, I call the function "BSP_HSPI_RAM_Config16BitsOctalRAM(...)"with my configuration set to use a 1K word linear burst.How...
