how big is spi buffer on lpc1768?
Hi,
exists on lpc1768 an spi-buffer or is it only possible to send one 8bit-word? I´m using lpc... als spi-slave.
When doing this several times on slave:
SPISlave device(p5, p6, p7, p8); mosi, miso, sclk, ssel
device.reply(1); device.reply(2); ... device.reply(30)
and this on master (python spidev on raspberry pi):
result = spi.read(30).
I only receive the first device.reply(1). The following values will not be sended. But when doing this on master:
for x in range (30): result = spi.read(1) print (result)
I can receive all 30 values from spi-slave.
Does function device.reply (value) on spi-slave putting only data into spi-buffer, when chip-select changes and data-transmit between bits?
