@user6350
Thanks a lot for your help.
Now the SPI works perfectly well, even I must check what you changed in order to have it working ( MISO pin ? ) and I immediately was able to get data from the accelerometer, but most important from the SD card.
It is to say that my last trouble was on the microSD card MISO pin.
I soldered by hand .5 mm wires on the rear of the small SMD card connector and by change the only poor contact was on the Card response (MISO) pin…
( I can say that Murphy law is really true )
Espruino is really a good design.
I can imagine what could be done when it will be ported to the powerful STm32F429 architecture.
