Ok, I got it – need to set the ctrl_reg0 ee_w bit. With that set the image registers change properly.
I’m having trouble setting BMA180 registers (eg, the range and bandwidth registers at 0x35 and 0x20) using a UBW32 PIC32 board.
I can read the version, gain, range, and acceleration values alright (using SPI with control byte with leading bit 1) but after writing (control byte with leading bit 0), a read returns the same value the register had before the write. I’m writing directly into the setting register, not the EEPROM register – the data sheet says this is read/write, but I can’t get the write to work.
Any pointers on what I might be doing wrong will be appreciated; thanks in advance.

Win7 doesn’t recognize this board as a mouse – I get an ‘unknown device’ error, says device gives code 43. Any ideas as to how to deal with this?
