In reference manual table 55 (Kernel clock distribution overview), there is a line for the DFSDM clock, indicating that it can be taken from either sys_ck or bus clock (which in the case of DFSDM would be APB2). That table also indicates that the max...
Hi. I'm trying to determine which flash bank running code resides in. I'm planning on reading the program counter and use that to determine which bank I'm in. Both GCC and the Arm compiler have some variant of a __current_pc() intrinsic. I haven't be...
Posted on August 27, 2013 at 11:24Hello,I'm currently working on a brushless motor control application and i'm in the process of implementing the current measuring of the three phases. In order to do so, I need to synchronise the ADC sampling with t...
I've got an issue that the STM32L432 on the Nucleo running a simple I2C I/F isn't working with a DHUT21 when exactly the same code on the 433 is fine. The same I2C code on both chips works fine with a BMP180 and many other devices. This is reproduci...
Hello,I do not find any encoding for the TSEL field in MDMA_CxTBR.. Probably they correspond to the list in MDMA-STM32H753_mdma1_v1_0_Modes.xml. But there may be reserved values like "54" in the DMA Mux requests , so they need to be documented somewh...
Hi there, I've configured my TrueSTUDIO in the following way: https://www.youtube.com/watch?v=qSzme7qcBb0, to redirect the output of my printf-function to console. It works, but the output is limited, sometimes if I want to output a bigger amount of ...
Hi Everyone!I am using the STM32407IG and i am trying to send data to another mcu chip via USART RX TX Pins.The Problem is when i run it via USB FS i don't get the baud rate adjusted.How can i setup the Clock for a Baud rate of 9600?That's my clock s...
I am using a particular pin as a timer channel for a PWM Generation signal. For some reason, this pin is always set to logic HIGH before I have the PWM timer begin. Is there a way to set this PWM pin to logic LOW, before the PWM timer begins? I am cu...
I am only using DMA to receive data continuously so when i want to receive data I am swithcing modes from full duplex to receive only. this whole pattern was working on F7 but not able to get it working on H7.I have followed some solutions given on S...
Posted on May 31, 2018 at 11:34Hi, everyone. I've been using STM32F030F4P6 for a project. While prototyping the circuit that I am going to use on my project, I shorted Vdda and Vdd pins together with 10uF and 100nF capacitors to the ground. I am giv...
