ideas ? |
It is a little "hole" in the project of the tma adapter 1.1. The usb cable is connected to the Pin 1 of the adapter (Vbatt); if you connect the TMA to the box and you start the program, the self test check all the configurations; one of the test is the Vbat .. test one Vbatt must be about 5 V if needed and this test pass.. second part is Vbatt must be 0 if needed but whatever the box sto giving power to the vbatt the test read 5 Volts coming from the adapter USB cable to the pin1 and you get the error. was enaugh one diode on the pin 1 to prevent this error..
Obviously this error doesn't happen with the tma evolution.
