# TC1 U4
Alternative firmware for U4 (STC15 8051 uC) on TransistorTester derivate TC1.
Use in Combination with https://github.com/svn2github/transistortester
## Compilation
This project is for Keil µVision IDE, which can be found here: http://www.keil.com/
You can either compile the fw yourself, use the latest precompiled fw in /Objects or download one of the released fw files.
## Connection
Just grab any kind of USB-to-UART(3V3) Adapter and hook up...
* TXD (Stick) to P1,
* RXD to P2 and
* GND to GND
Alternatively you can either desolder it and use some SOP8 ↔ DIP8 socket converter
or a SOIC (SOP8) test clip.
## Upload / Flashing
Download the STC-ISP Software here: http://www.stcmicro.com/rar/stc-isp6.86.rar
Open it but leave everything as it is, except:
* Input IRC frequency
which is set to 12.000 MHz.
Press "Open Code File" and select the firmware (u4.hex).
Press "Download/Program" and hook up 3.3V from the programmer to the chips VCC (power the IC).
Wait for the firmware being uploaded.
