Resolved! 2 channels of DMA won't work
Hello, I'm trying to use 2channels of DMA , one for PWM in timer1 and one for reading adc1 using timer3 .dma c2 should give ccr the amount from a uint string[1000](which i deleted from this code for simplifiing to be easier to read) and dma c1 for r...
Wanting to use external interrupt to turn on internal led.
I am not wanting to use the HAL interface because I want to try and gain experience with the ARM bare metal programming. I have examples online and seem to be following them exactly but the led will not light up when a pin is pulled to ground. I meas...
STM32L151CCT6 Freezes when enabling HSI
I have an application where we have the mentioned MCU using the HSI passing through the PLL to achieve 32 MHz on the main clock. But we noticed that the MCU freezes after executing the instruction for enabling the HSI, and as this is an internal circ...
OctoSPI Polling Sends too many bytes
I've got my OctoSPI interface working for NOR reads and writes, but Auto-polling is sending too many bytes. The Data Length Register (DLR) is set to 0, for one byte of data, but I get the instruction plus two bytes. If I set the DLR to 1, I get...

Resolved! Nucleo-U575 board, what is the magical "OSV bit", mentioned in the guide only once??
Hello again everyone, I have been still looking at the ADC1. The thing is, in the User Guide Bible page 1031, "Managing conversions using the DMA" section, there is a phrase, that says: "The DMA transfer requests are blocked until the software clears...

STM32G0 series TIM+ADC+DMA. Why does an external event not come from the timer?
I have had an experience of working with TIM+ADC+DMA on microcontrollers F series. Now I need to use TIM+ADC+DMA on microcontroller STM32G030F6P6. A part of ADC and DMA registers was changed in G0 series. I want to digitize sequencely two channels af...
Resolved! STM32F207 access data to beyond flash size
I have STM32F207ZE and made a project that read and write data to flash memory.STM32F207ZE flash size is 512Kbyte.but I tried writing data to a 0x80E0000 address(flash sector 11), it worked.Surprisingly, the STM32CubeProgrammer can also has access ...
