I am trying to identify this 32 pin chip (23257-B) used in an automotive application (see picture). I am unable to locate any spec sheets. I am pretty sure it is a variant of the STMicroelectronics ST72324 8-bit microcontroller. Can anyone confirm a...
I'm using the SPW04SA module and want to write sensor data to the Azure Storage Table service. To achieve this I have to add special headers to my requests.Until now I couldn't find out if/how this can be done using AT+S.HTTPPOST and AT+S.HTTPGET. As...
I want to communicate with the wifi module integrated in the STM32 iot node using AT commands, so i configure the internal uart3 used by the module to receive AT commands and transmit the answer to the AT command but it doesn't work ?
Does anybody have this L9678P typical circuit and could you explain the component select method and IC pin function?
I used spice model downloaded from ST product page. But model behaviour is highly strange in LTspice XVII. There is 60V Gate voltage in I. and IV. quandrant. Negative gate current turn triac ON only in one quadrant.Is it possible to use ST models in ...
I am trying to see if a chip marked "23257-B 1MU2114" is a predecessor to the ST72324 8 Bit MCU. It is used in an automotive application, and the documentation says the chip on the board should be an ST72324, but the "23257-B" is there instead (see p...
Hi ST10F276 group,we have used St10F276 many years. It works very well. But one project generated random NMI trap recently, and crashed the application. My question is how I can back to user application from NMI trap (interrupt)? So far I only can...
I'm using the SPWF04SA module to write sensor data to Azure Storage Table service by sending https POST request over a socket connection. The application works fine for some hundred requests over several hours but occasionally a WIND: NtpServerDelive...
I want to #know if I can #create Topics with #hashtags. And further if I say whodunnit.io does it turn into dummy hotlink?
