I am using STM32F103C8T6, timer 1 ch 1 to generate complementary PWMwith variable duty cycle Using DMA buffer HAL_TIM_Base_Start(&htim1); HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *) base, 30); HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANN...
Hello, I am a little confused here, AN392 claims to run STM32C0 from a 5V power supply, directly from the main fed RCD dropper with a 5.6V Zener. But the datasheet says the maximum voltage is 4V.So does the AN suggest running way over max specs or is...
Good day everyone,I am currently implementing an update process and I am facing some issues if I want to erase the internal flash memory sector if my code is running from an external OSPI-Flash. I am getting the errors:Read Protection ErrorRead Secur...
Posted on July 28, 2015 at 23:04 I'm trying to set Flash read protection, so I run this at startup: if (FLASH_GetReadOutProtectionStatus() != SET) { FLASH_ReadOutProtection(ENABLE); } This works wrt read protection, in that if I ...
I was trying to use FDCAN when I came across a problem where FDCAN_CCCR.Init bit is not getting cleared. The CCE bit gets cleared when setting INIT to 0, but INIT stays unchanged. Any ideas what could be wrong? I came across this topic where they had...
Hello,i have implemented USB Host CDC in my controller using STM32CubeMX and also taken reference from the link : https://controllerstech.com/usb-cdc-device-and-host-in-stm32/#:~:text=HOST%20Setup,Leave%20everything%20here%20to%20default.aken the ref...

I am trying to use the F103 as a I2C master but it is holding the I2C pins low, there is nothing else on the bus 5k1 pullups, when I hold the device in reset the lines are 5V. Because the lines are low, SB is never being set, so the first while state...
I am getting the above warning! I am unable to find what is causing the issue. If I comment the line number 5442, then no warnings or no errors. Help me resolve this issue.
Hi,For the SPI transfer APIs with suffix '_DMA'. In the transmit and receive alone ones, they checked 'hspi->hdmatx' and 'hspi->hdmarx' respectively. But in 'HAL_SPI_TransmitReceive_DMA()', it only check the 'hspi->hdmarx'. Funny :), and why? /* Pa...
