Discuss hardware and software design challenges, including NOR flash storage, OTA updates, component ID, and thermal management.
STR73xx MCU's are old, but I think the CAN operation is similar to newer parts. This part supports loopback and loopback with silent options. I am interested in the one called just 'loopback'. In loopback, the TX pin is active, but RX pin is disconne...
I read the CAN section of the RM0001 Reference manuaI STR73x ARMTDMI microcontroller family a few times, but still don't understand how to set acceptance masking and filtering. I want to only accept CAN extended messages with 29 bit headers that matc...
Hi everybody, I am kindly new to the EMI requirement field. I am currently designing a stepper motor control board based on a L6470 driver. I have strict EMI standards to meet so I am thinking about filtering the noise and perturbations caused by the...
Dear，Could you kindly help provide MTTF/FIT for LMV321ILT

Hi everyone,I recently got a ZY-2.1BT 2.1 channel Bluetooth digital power amplifier board to test out as part of a DIY audio setup. The idea is to run two bookshelf speakers plus a subwoofer from a single board, mainly for a small home theater projec...
Hi there ! I hope someone can help me with a confusion i had in my mind right now. I work with a EEPROM 24C256 and need a write a lot of data inside , soo i decide to use the page write solution . So from the datasheet i saw i can write 64byte in one...
Hi there. I require assistance to ensure the proper operation of GT9271.After properly RESETting the GT9271, and issuing the 0XBA I2C address, the device keeps pulling the INT pin without any touch on the LCD display (1024x600). I really feel a lack ...
Dear Sir,I reviewed UM1748 User Manual for EVALSTPM34, EVALSTPM33, EVALSTPM32 evaluation board.Below is described in the contents.===========================1.3 Recommended readingsThis document describes how to use and set up a basic test session wi...
”Switch S1 is ON (connected to common port D) when the IN input is held high, andOFF (a high impedance state exists between the two ports) when IN is held low.Switch S2 is ON (connected to common port D) when the IN input is held low andOFF (a high i...
