Posted on June 12, 2018 at 12:41Hi all,I have a board using the STM32F765, which uses the QSPI interface to fetch data from an FPGA. The normal sequence of operation is: A timer in the FPGA causes it to perform a sequence of events which produce a ...

I need to whip up a quick daughter board (shield?) for a Nucleo 144 board (F429 discovery).Are Eagle CAD files available (with board outline, connectors, power+signals, ready to add our components)?Thanks!Best Regards, Dave
Hello all,I built with CubeMX 5.0.1 a project from scratch using the default settings.The modifications:MMC --> SD (otherwise it wouldn't run. Probably ST will change it someday)LWIP enabled with fixed IP addressesAdded two lines to blink a LEDCompil...
How many erase / write cycles is the flash inside the STM32L475VC good for?Thanks.David Smith

Posted on March 23, 2017 at 14:12I think that there is dangerous a bug in the cmsis_os implementation, because when you create a queue (thru osMessageCreate), it creates a queue in FreeRTOS with the item size based in the item size configured by the...
Hi, I'm having a doubt related to HSYNC, VSYNC and Porch Calculations. I'm working with STM32F746G Disco Board and wanted to understand how these values are calculated. The HSYNC, VSYNC, HBP, HFP, VBP, VFP values mentioned in data sheet (https://cach...
I got the latest CMSIS from github and tried using the DSP code on a STM32H743ZI chip. I call three APIs which are:arm_cfft_f32()arm_cmplx_mag_f32()arm_max_f32()The code compiles fine with GCC but when it comes time to link I get a 'undefined referen...
It's an expected behavior that Flash could be corrupted if the write operation is interrupted, such as by power loss or reset, as stated in RM0360, RM0444 etc.But there is no information about the distribution of the corruption. Only the data writing...
