WIFI Multi-channel Power Meter (bl0906+esp8266) All-in-one Version

Overview

Modify the original project to directly integrate the 8266, requiring only one board and making it easier to use for free.
Considering space constraints after integration, replace the power module with a Prida one. Since
I had a Prida 5V module on hand, I added an LDO circuit. If you purchased a 3.3V module, you can remove the LDO section.
Change the voltage transformer divider resistor from 2010 to 0805; testing showed no problems.
You can replace the 8266-12F with a C3-12F for potentially better performance and Bluetooth support. If you're concerned about signal strength, you can add an IPX connector to the C3F to connect an external antenna.
The ESP8266-12F can be replaced with an ESP07s;
the procedure for connecting an external antenna is the same as the original project, but please modify the serial port to tx:5, rx:4.

Looking for learning videos
If anyone has a learning video of msp430, please send me one, thank you
The tim1 in M0 is not used well, and it always fails to enter the interrupt
I originally found the routine for tim2 and changed the configuration to tim1, but then the debugging did not enter the interrupt. I want to ask if tim1 needs to configure some special registers?
Bluetooth development outsourcing
Has anyone done secondary development of Bluetooth SIM cards? Or has more development experience for BLE 4.x? If so, please contact me on the site. I need someone in Shanghai or Hangzhou.

What does the data obtained by ADS1211 mean?
I use an inductive micrometer to get the shape error signal, and after conversion by ADS1211, it is stored as a character and then sent to the host computer. Can the host computer have decimal points
