Hi,I am trying to control a lot of RGB leds at the same time through TLC5955 RGB SPI controllers/I have 11 of them daisy chained to my STM32F7. Each one of them needs 1 bit (0 for data transfer) and then 768 bits of data (96 bytes). As you can see da...
Hi.My code generation is almost done. I want to lock the code so that no one else can conveniently reach and use my code. I want that for future development to erase the code and reprogram it. I read some information provided by ST and I think I have...
Hello,I need to connect a STM32 to an ethernet peripheral that will send periodially an UDP frame on a specific port. I just have to listen on the port and handle the measure.Ethernet speaking, is there any problem or modification required to handle ...
Hello.I am working on a project and using STM32L053 board.For now, my goal is to create a channel of SPI communication, master & slave, an to test my code.I am using only 1 ST board which serves both as master and slave. I have defined all necessary ...
Purpose is to generate 4 mutually phase shifted PWMs. Regular master/slave mode will require 8 timers in that case (right?). So thought of using the following, if possible:TIM1 = master to TIM2, TIM2 = slave of TIM1 and master to TIM3, TIM3 = slave o...
ex) When compiled with IAR 8.30.1, HardFault exception was occured.float gfSetDataRate = 100.0f; printf("Data Rate = %f \r\n", gfSetDataRate);HardFault is occured at VCVT.F64.F32 instruction.I also tested following caseIn case Compiled with GCC, is...
Hello,I am trying to convert a project generated by CubeMX to a C++ project in Atollic True Studio.From various sources, I got hints how to do. I fail when trying to copy the symbols e.g. processor type to C++ because the input pane is missing. Here ...
Hi Folks, I recently had a hard drive crash so I had to re-install Atollic Studio and the Cube32MX programs. My original project was read by the Cube32MX just fine but when I clicked on the Generate Code button it'll chug for a while and this error p...
