I have configured a UART to receive in DMA mode where the size of the buffer is around 64 bytes. So, basically the HAL_UART_RxCpltCallback() DMA receive complete interrupt will only fire when 64 chars are received. Is there a way in STM32 through wh...
The Reference Manual of the STM32L1 talks about "Up to 40 external I/OS can be used far data acquisition purpose in conjonction with the ADC interface".The ADC_INxx pins number is smaller...I saw that we can root pins with the "Routing Interface" per...
I was trying to figure out what datasheet says with the following sentence highlighted bold for STM32F303R8T6The PWM mode can be selected independently on each channel (one PWM per OCx output) by writing ‘0110’ (PWM mode 1) or ‘0111’ (PWM mode 2) in ...
Hello!I have problem with Tick functions in this firmware."HAL_GetTick()" function always returns value 0.Also some functions that use timeout doesn't exit on timeout situation because they count on "HAL_GetTick()".Could somebody help me to start Tic...
Posted on August 22, 2017 at 17:25Hi,I am trying to use the STM32 flash loader demonstrator to download a new software on my device.I am using the version V2.9.0RC4, which I have found on this site (Cf. https://community.st.com/0D50X00009XkYFUSA3 )....
Hi,I'm trying to load the LedToggling applicaton into the STM32H743I-EVAL board compiled with the XIP_QSPI_InternalSRAM configuration and using the EWARM.It is written in the readme.txt file that for the EWARM I only have to use is Project->Debug. ...
Hello, I'm using stm32l152re nucleo board and I've to connect an accelerometer with I2c. All is ok, but when I build the project the linker says "Undefined reference to HAL_I2C_MASTER_TRANSMIT". That's a function of stm32l1xx_hal_i2c.h and I can't un...
Posted on January 09, 2018 at 18:32Hi,Using CubeMX, I configured SPI1 on a STM32F103T8Ux as full-duplex master mapped on PB3..PB5, with hardware NSS (on PA15) disabled (set to SPI_NSS_SOFT in spi.c).So, PA15 should be available for TIM2 CH1 PWM outp...
Hello,I use STM32H743ZI two SPIs with DMA to collect data. The data are OK when only one SPI with DMA is activated. However, when I use two SPIs with DMA to collect data simultaneously, the data collected are not correct. The DMA setup:Codes to colle...
