I’m having some problems with a subroutine in the small program I’ve been working on mikroBasic for the Honda Music Link stuffs I’ve been doing.<\/p>\n

Could any of you help me?<\/p>\n

To start, here’s a copy of the program in a text file: hml_mikrobasic_help.txt<\/a><\/p>\n

Here’s the project itself, zipped up: hml_mikrobasic_help.zip<\/a><\/p>\n

The IDE \/ compiler itself, mikroBasic, is available here<\/a>. <\/p>\n

(I’m just using the demo version, and the limit is only on code size, so feel free to install it. I don’t come anywhere near the code limit, and when one does it’s rather obvious, as the compiler just refuses to compile it.<\/p>\n

The problem I’m having is with sendCommand()<\/tt>, and specifically the variable iPodCommand<\/tt>, which is the first one passed to it. What I expect to happen is that whatever is passed as the first argument to sendCommand()<\/tt> will be set and available within the procedure. Instead, I seem to be getting something else.<\/p>\n

As the program is currently listed, I would expect the output sendCommand(powerOn, 0)<\/tt> to be 0xFF 0x55 0x04 0x00 0x00 0x00 0x04 0xF8<\/tt>. However, the output I receive is 0xFF 0x55 0x02 0xFE 0xB9 0x47<\/tt>.<\/p>\n

The expected packet is broken down as follows:<\/p>\n

0xFF<\/tt> – Header 1
\n0x55<\/tt> – Header 2
\n0x04<\/tt> – Data Length
\n0x00<\/tt> – Data 1
\n0x00<\/tt> – Data 2
\n0x00<\/tt> – Data 3
\n0x04<\/tt> – Data 4
\n0x08<\/tt> – Checksum (0x100 – Data Length – All Data Packets)<\/p><\/blockquote>\n

The received packet breaks down this way:<\/p>\n

0xFF<\/tt> – Expected Header 1
\n0x55<\/tt> – Expected Header 2
\n0x02<\/tt> – Length appropriate if the constant referenced by iPodCommand<\/tt> were two bites in length.
\n0xFE<\/tt> – Data 1 (Not sure where this comes from.)
\n0xB9<\/tt> – Data 2 (This one neither…)
\n0x47<\/tt> – Checksum, calculated properly off of unexpected Data bytes.<\/p><\/blockquote>\n

When I run things through the hardware debugger I’m not seeing the variable iPodCommand<\/tt> as an array, and I’m not sure why or how (it just shows a value of 0xDF<\/tt>). That, though, and it’s not working as expected, is leading me to believe that I’m doing something wrong in setting up sendCommand()<\/tt>.<\/p>\n

So, could any of you please help me? I just don’t know what I’m doing wrong.<\/p>\n

Thanks!<\/p>\n","protected":false},"excerpt":{"rendered":"
