Hello,
I have good news today.
First, we figure out, with the help of Samuel, why our USB port was broken. We had a 6 Mhz clock wherease I though it was a 8 Mhz, as our schematic says.
Secoudly, our H Bridge works as expected.
The alternative intensity that is going through the coil have a magnitude of 1.1A.
And we have 20 periods to make our measures, a little more than expected.
Concerning my concerns for the heat, we are border line. We can’t increase the intensity.
Aside from that, today I have finished to code the interface, using ZeroMQ, between NodeJS that handle the BLE and the calculator.
Woohoo !!
…put it in a fish tank and keep pushing the power ;p
