What is the relationship between SPI clock and compiler optimization on STM32L0 ?
Hi,I'm working on a custom board where we integrated an STM32L010RB and I have verry weird behaviour :I need to use SPI1 peripheral and the clock signal is working as expected only if I enable optimization on the compiler settings.The MISO is OK. In ...
Resolved! Flash Programming Error Even if Flash was erased.
Hi guys,I am using and STM32L552ZET6 and I get a behavior I can not exaplain. The device is power at 1.8V in case it matters. So to put it shortly I have 2 blocks of 8 pages each. At first start I erase both of the blocks and write only in block 1 so...
CPU test bug in the X-CUBE-STL (gcc)
Hi, this isn't really a question, but I figured I'd share back with the community (and hopefully bring the change back into ST's next release) on the X-CUBE-STL CPU test code.There are some instances, where the APSR has some bit set in what ARM docum...
using STM32H750XB ADC to read 4-20mA transmitter signal
Hi,How to connect to the preamp in order to use smaller R and reduce the voltage drop, the reference manual table below is not clear to me, particularly the internal column, please see figures below.
Resolved! STM32F429ZI interface to GEN4-FT813-CTP-CLB:
Everyone, Posting for the first time here. We've been working with a 4d display that's based on an FT813 IC. The issue that we came to so far is the following.0x7C during Initialization is never detected although, it is detected from MISO. This is re...

How to manage 2 channel PWM with DMA - STM32L073
We try to generate audio signal with 2 PWM signals. We use TIM2_CH1 and TIM2_CH2 with DMA1 channel 5 and channel 3. This two PWM signals must be synchronized, but we noticed some delay between this 2 channels, which unfortunately is not constant. For...
In Rx Polling Mode, HAL_UART_Receive() is stuck in UART_WaitOnFlagUntilTimeout() waiting for the RXNE flag to get set in the UART's Status Register.
I'm using a STM32F407-Disc1 board, and my polled HAL_UART_Receive() is stuck waiting for the RXNE flag to get set in the UART Status register. Ironically, when using the STM32CubeIDE debugger and looking at the SFR registers for my UART, it looks li...
STM32U5 ADC internal channel
Hello,I'm facing some issues sampling ADC internal channel in of STM32u575.In particular these are the steps I'm following:VDDA enableADC Clock ConfigurationHAL_ADC_Init (&ADC_Handle[i])Interrupt configuration.Then, I configure the ADC channel to rea...
