How to implement SPR PPS Mode for the STM32F072 ?
Hi, I am using an NUCLEO-F072RB Board with an STUSB1602 Type-C Controller Expansion Board. My Goal is to program a Sink application which is able to use the PPS Mode. Furthermore I am using the STM32_MB1303_SNK_ONLY Project as a reference. My Questio...
STM32L151 SPI in interrupt mode unable to send from within interrupt
STM32L151 running at 32MHZSPI prescaler 256 running at 125KBits/sThe interrrupt does fire, but the first call (from non interrupt context) to get the transfer started HAL_SPI_Transmit_IT hasn't yet finished.Reason: In HAL_SPI_Transmit_IT __HAL_UNLOCK...
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...
Resolved! Variable runover before it reaches its limit
Hello everyone,My variable had a Runover even before it reached its range.Currently, I am working with timer 2 with a frequency of 90MHz. When I retrieved the current time by `__HAL_TIM_GET_COUNTER()` and printed it by `printf("receive_time: %lu\n", ...
