Resolved! How does STM32F429ZI MAC controller know when Collision occurs?
Hi I am currently working on a project where I have to implement TCP/IP stack on STM32F429ZI 144 pin nucleo board. Board has PHY chip.My question is how does the MAC controller knows when a jabber or collision event occurs since these events are hand...
Documentation on SPWF01SA module
I have to support a legacy product with SPWF01SA module.Looking for detailed documentation on the module (not of the Nucleo shied).I know that it is obsolete or NRND or whatever, but still need as much details as available.Any pointers?
Help to understand the work of latching in STPM chips
I work with STPM34 and STPM33. I want to make a relay protection terminal with it. You have to take readings very quickly. Every 20 milliseconds.How i think it working:1) RMS current and voltage registers count RMS value 200 milliseconds and then the...
LSM6DSM not sending data
Hey,I am using an LSM6DSM with a 32bit MCU,I am using the generic C code provided by STM,I was able to configure it and get inital readings but after some time,it has stopped sending reading ,I am checking the "status_reg.xlda" value to check for new...
BLUENRG-2 constantly wakes up, settings when IO11 is low.
I have an application where I wake-up the BLUENRG-2 source from IO11 is low. but its not work. as a debug I config UART On Tx IO4 & Rx IO 5. for wake up and sleep I print sleep and wakeup. its continues print wake and sleep. when I set IO11 to GND, o...
Resolved! Is it possible to reprogram the serial bridge firmware (STM32-F103xx) on the BlueNRG-LP if the serial communication is no longer working?
I was not able to find the answer to this in the QA/Knowledge Base. I understand ST documentation says not to mess with the STM32-F103xx as it comes pre-programmed from the factory. However I have a board whose serial communications between the hos...
