We are interfacing a Chafon MU910-M UHF RFID reader module with an STM32F103C8T6 (Blue Pill) board using UART communication. During loopback testing, we observed that individual UART ports are functional and can transmit single byte, but when attempt...
Hi,Im analyzing the circuit of the STGAP3SXS in EVLSTGAP3SXS-.I want to ask what's the purpose of this capacitance in the soft off pin, I thought it was filtering by why does it go to the VL instead of GND_ISOThank you.
Hello,We are testing the st33ktpm2x as a secure key generator and storage on our raspberry cm4 running openwrt (kernel 6.6), but came across some problems when trying to access the device.When we connect it via the i2c1 and use the dtbo provided from...
Greetings Community,I am using the STHV800 ultrasound pulser in the analog front-end of an ultrasound imaging application. In my setup, I pulse at ±50V, generating a 3-cycle biphasic signal at 5.2 MHz for transmit. The transducer is connected via a 2...
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! I have a cirquitboard that contains a component of ST mark. It is a surficemounted component thatlooks like a diod with a stripe in one end. It is marked DX 63 450 utt i can not find this component onyour side. Can yoy help me?/ Bjoern
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...
