Hello. I'm working with the USB4715EVM and messing around with the Configuration registers using the MPLAB Connect tool. By default, the digital mics are not enabled. I know this by sniffing the I2C writes from the hub to the codec and seeing that codec ADAU1961 address 0x4019 is being written as 0x..
I am using microPython on an ESP32. I2C is at 100KHz. I have had no difficulty in setting the output of this DAC but have not been able to change the I2C address. The datasheet is not very clear on this. It is not clear whether to use the disable or enablecommands to unlock it. With 10V on LDAC I ha..
Hello I'am working with the ATM90E36A and ATM90E32AS Thee phase Energy meter project. I have seen that SPI SDO is always on high impedance state. so no response from ATM90Exxx...
Dear Forumers! I am using the MCP33151D chip for high quality audio signal acquisition. My problem is, that in case of rare events, the ADC chip continues to keep it's SDO in high state, instead of providing the actual measurement results. I have just discovered, that the documentation restricts any..
Hello. I'm using the USB2532 in an application that utilizes the UART bridge functionality. Is this UART bridge support CDC ACM? Other than initializing the UART bridge via configuration registers, is there anything I need to do to get it to support CDC ACM? Using the USB2534 dev board, I've got the..
I am looking at using the MCP37D11-80 in a measurement device for my research work. My measurements are taken using resistance-based strain gauges in a wheatstone bridge configuration. Typically, I modify this signal with an amplifier for measurement with an oscilloscope since the measurements can b..
I'm planning to use the Microchip LR645 linear regulator in a non-isolated power supply, datasheet ( states that LR645 is capable to deliver up to 150 mA output current using an external depletion-mode MOSFET DN2540 (MOSFET DN2625 ( also from Microchip is another depletion-mode MOSFET with very simi..
Using voltage regulator MCP1703T-5002E/CB
Input voltage: 12V Output: 5V
Filter cap on output: 1u ceramic X5R 0603
The only load for this regulator is an analog VCO IC SSI2130:
It draws about ~3mA and there is no crazy inrush currents o..
The datasheet of the MCP39F511 says that if an external clock source is not detected, the internal 4MHz oscillator will be used. I wonder, what if the external crystal is not working? I understand that we run on the internal clock source, but this might be problematic. Is there any possibility to ch..
Hi Can anyone suggest an appropriate MCU to read 2 50 hz PWM signals that were supposed to be destined to hobby RC servos and be able to output 4 code derived variable analog voltage signals between 0.5V to 5 V at only 100 mA as well as 8 digital (binary) outputs for control as well ?The analog sign..
