设置SPI多个片选引脚除了config里面定义的其余引脚是否需要用GPIO虚拟，同时虚拟出来的引脚对传输速率是否有影响 可以使用GPIO模拟，在每次SPI发送之前，对SPI的片选信号也会进行控制，所以SPI的片选信号就是在每次需要发送到某个设备的时候，将CS片选端进行 ...

We used CCS Theia 1.3.1 command line for automatically building projects. Now we update the CCS Theia to 1.5.1. But we find that build command will not return error ...

I have an industrial project where there will be one master controller connected to six (6) slave controllers. The physical location of the plant is such that it would be very much feasible for me to ...

I have some question s on the fueses. this is not only relates to TPS2HCS10-Q1, but in generakl for the HCS -Family. I have following questions: Standby - Active Mode of MCU eFuses must be active even ...

We are seeking assistance with a Flyback SMPS design using the UCC28750 controller. The design was based on the UCC28750EVM-071 User Guide and the UCC28750 Datasheet. At no load, the output reaches a ...

This is due to the internal 100k pull-up resistors that cannot be disabled within the IO expander. This is why there is a difference between HIGH and LOW inputs. LOW inputs will cause current to flow ...

2)VIO pin required & supply voltage level is 3.3v 3)Should have CAN Signal improvement capability as per CiA-601-4 standard I am seeing the potential of TCAN1042-Q1. Will this work with the ...

we have a microelectronic system which draws power from the REG1 configured to supply 3.3V when the battery pack is connected. However, when the battery pack is not connected, we will supply 3.3V from ...

What is the difference between the schematics from Figure 1 DRV425EVM and Figure 2 from TIDA 00463. In figure 1, The shunt resistor is on the trace bewteen DRV2 (Pin 11) and COMP2 (Pin 17) In figure 2 ...

Vin: I created a circuit that boots from 5V to 6.3V and converts it to 5V with a regulator, but when I connect a 100mA load, Vout drops to 5.3V. Can you catch a waveform of the unexpected Vout drop.

i bought for my private study a launchxl-f28379D and launchxl-f280049C , i've never had an experience with that mcu's before . I'm using a CCS version 12.6.0.00008 on Win11 . I had a problem with ...

We have encountered a boot up issue with TDA4AL at -40 degree C. The boot up process hanged and cannot be recovered even we try to reset the PMIC power on process. The boot process kept the same ...
