Include type, description and units to each data
Each data should have a description, its type and units.
Good example: https://github.com/bluerobotics/ping-protocol/blob/master/src/definitions/ping1d.json#L358
Implement the file exporter for .h
Implement a way to describe modules variations
Implement a way to describe modules variations, like different signatures, specifically to be able to describe the voltage/current sensors (MSC19).
Verify consistency
For now the consistency of the protocol is not guaranteed.
At least it needs:
- to check the data types before describe bytes and bits, also before add topics and modules.
- to check for any duplicated modules ids and topics ids before import or export.
Describe all topics from all modules
List all modules and its topics, then create a python script describing them. Ex:
from can import Can
can = Can()
m1 = can.module(...)
t1 = can.topic(...)
t1.describe_byte(...)
t1.describe_bit(...)
...
m1.add_topic(t1)
can.add_module(m1)
...
can.export_json("can_ids.json")
can parser types: values with more than 1 byte are generated wrong
when values are separated in bytes all parts are with the total size, instead of the size of the part
Example:
// Auxiliar Battery Voltage
typedef struct
{
union {
uint8_t raw[8];
struct {
uint8_t signature; // Senders signature. Units:
uint16_t batvoltage_l; // Battery Voltage, byte low. Units: V/100
uint16_t batvoltage_h; // Battery Voltage, byte high. Units: V/100
uint16_t position_l; // Tail Poisition, byte low. Units: °/100
uint16_t position_h; // Tail Poisition, byte high. Units: °/100
uint16_t batcurrent_l; // Battery Current, byte low. Units: A/100
uint16_t batcurrent_h; // Battery Current, byte high. Units: A/100
};
};
} can_mde22_steeringbat_measurements_msg_t;This should be:
// Auxiliar Battery Voltage
typedef struct
{
union {
uint8_t raw[8];
struct {
uint8_t signature; // Senders signature. Units:
uint16_t batvoltage; // Battery Voltage. Units: V/100
uint16_t position; // Tail Poisition. Units: °/100
uint16_t batcurrent; // Battery Current. Units: A/100
};
};
} can_mde22_steeringbat_measurements_msg_t;Or:
// Auxiliar Battery Voltage
typedef struct
{
union {
uint8_t raw[8];
struct {
uint8_t signature; // Senders signature. Units:
union{
uint16_t batvoltage;
struct{
uint8_t batvoltage_l; // Battery Voltage, byte low. Units: V/100
uint8_t batvoltage_h; // Battery Voltage, byte high. Units: V/100
};
};
};
};
} can_mde22_steeringbat_measurements_msg_t;Use Hypothesis in tests
