We have today started work on our next module, the Accra counter module. The hardware is already done. This unit will be able to count pulses on four channels and also measure frequency on each channel. It can have alarms set for going over a counter level or when counting down to zero and for a frequency that is outside of a specified frequency range.
It has a built-in linear calculation algorithm that can translate pulse to real world measurement units. This can for example be used for utility meter measurements and gives the correct measurement value sent out on the VSCP bus.
Kilafors will be supplied later as an add on modules to detect S0 (IR) pulses so that Accra can be hooked on to an electrical meter and output power usage data.
This will be the seventh module in the CAN4VSCP series and will be followed by Vilnius for 12-bit A/D measurements.
The module has ten 5V channels that individually can be set to either an input or an output.
Each output can have a pulse automatically generated.
Each channel can have a protection timer associated with it which turns it off after a specified time. This can be used as a security feature so that a critical controlled resource is not kept on when a communication line has been lost but can be used to keep an output on for a specific time for other uses.
TurnOn/TurnOff or On/Off events can be generated when signals go high/low. This is valid both for inputs and outputs. Perfect for monitoring systems or for autonomous control of other VSCP modules.
Alarm events can be generated when a pin change state. Perfect for alarm setups.
State of inputs/outputs can be streamed with configurable time interval.
Inputs can be used as button inputs with repeat.
The Beijing module have a decision matrix with eight entries that can set a pin high or low, toggle a pin, send status for a pin or all pins, or turn on/off pulse on a pin. This makes it easy to construct autonomous systems.
The module can be wall mounted or attached to a DIN rail as all modules in the CAN4VSCP series from Paradise of the Frog.
Almost done. It’s always the hardest part. I have never really understood why. So now for the Beijing I/O module I only have to verify that the input and debounce events work then I can stamp “ready” on the project or at least dub it “ready” as in firmware release 1.0.0. Yes and after that start coding on the next project. Going in to virgin land with a free mind. I like that. More than most other things in the world. But now, so close to the finish, I resist and slow down as always. Just as a runner that is close to the finish line usually does.
Yes I am tired. I have been working hard this year. Sixteen hour days for most of the days of the week. Month after month. Just as I did last year and the year before that and so on. Getting very little in return for my work. But not for a minute hesitated that this is something good. Yes I still believe in this.
So I have to pick up some strength from somewhere in myself and finish this. I really need to put “ready” on two other modules also before I go on vacation with a mind in rest. Is that even possible? Well I don’t know, I just know I better get on the job again right away.
Verifying the Beijing module. All is well up to now I can tell you. But a lot of functionality to test so things takes time as always. The Accra and the Vilnius modules are standing impatiently here in queue to be tested also including some other modules. Soon we move up to Ethernet, Bluetooth and Wifi.
No that ugly LED array is not part of the board. 😉
