I am starting a product design tentatively using the STM32F072RBT6.I want to determine how soon the CTS input must go low to prevent the USART from transmitting the next byte.Even informed opinion would be appreciated; but a reference to documentatio...

I added a c source file to an existing folder in my project and it shows in the project explorer.When I build the project or build the individual file it appears to compile (in the console). But references to functions in the file come back as undef...

Can someone shed light on what I am seeing?I was trying to validate the set up of one counter using the ISR of another counter. While the program was running I placed a break point in the code to stop and read the values. The difference values read f...

I created a project for the Nucleo-F207 board using FreeRTOS and LWIP that worked. But when I tried to re-create the same project for the -F429 it did NOT work. [However the -F207 binary did work when loaded on the -F429 board.] On the -F429, DHCP...

I managed to get a simple TLS client working on the NUCLEO-F207ZG. I cannot get the program to run on the NUCLEO-H743ZI2. On Wireshark I see several DHCP DISCOVER messages go out; followed by an OFFER message coming back. My code never responds with ...

So, I ordered an eval board and measured the CLS latency.Yellow Trace = USART TX data (run thru a high pass filter; data byte = 0x00; The low going pulses are the beginning of a TX.)Blue Trace = CLSBaud Rate = 4800fck = 48MHz (21nS period)After runni...

Thanks for your help.What about the case where there is a gap between the characters or the first character in a message. That is why I think they really mean "before start of next character". Also CTS has no effect on the current character - only ...

You don't say in what way the data is wrong. Is is garbled bits, missing bytes, repeated bytes?Obviously, since you a operating as spi master, as a work-around you could just force a pause between bytes.

I am not sure where to look for those parameters - but it only fails on this one new file. In all of the other files in my project the editor grays out #ifdef'ed code.Does each source file somehow have separate editor settings?

paulrbryson · 2022-10-17

I found the problem.The editor was not properly indicating the state of an "#ifdef", i.e. it did not gray out the code even though the value was not defined.I have come to rely heavily on this feature.I guess the question now is:"Why doesn't the edit...
